Serostatus refers to the presence or absence of a serological marker in the blood. The presence of detectable levels of a specific marker within the serum is considered seropositivity, while the absence of such levels is considered seronegativity.
HIV/AIDS
The term serostatus is commonly used in HIV/AIDS prevention efforts. In the late 20th and early 21st centuries, social advocacy has emphasized the importance of learning one's HIV/AIDS serostatus in an effort to curtail the spread of the disease.[1]
Autoimmune disease
Researchers have investigated the effects of autoantibody serostatus on autoimmune disease presentation.[2][3][4] Study of seronegative patient populations has led to the identification of additional autoantibodies that could potentially help with diagnosis.[5][6]
